In order to explain the known anomalies in water, some researchers assume that water consists of a mixture of two phases even under ambient conditions. However, new X-ray spectroscopic analyses show that this is not the case. At room temperature and normal pressure, the water molecules form a fluctuating network with an average of 1.74 ± 2.1 percent donor and acceptor hydrogen bridge bonds per molecule each, allowing tetrahedral coordination between close neighbors.
